EFFECT OF DIFFERENT KINDS AND RATES OF ORGANIC FERTILIZERS ON THE NUTRIENTS BALANCE AND CHANGES OF AGROCHEMICAL PARAMETERS OF SOD-PODZOLIC LOAMY SAND SOIL

Abstract

In studies on sod-podzolic loamy sand soil the one-sided application of organic or mineral fertilizers in crop rotation link corn - spring rapeseed - winter triticale has not supplied the getting of self-supporting nitrogen and potassium balance; at organic-mineral fertilizer system the nitrogen balance ranged 16-53 kg/ha. The chicken manure application provided the positive phosphorus balance with the intensity of 189-307 %. The application of peat-lignin-straw- manure, peat-sugar beet presscake-defecate filth-straw-manure composts and organic-calcareous, siliceous sapropel promoted to soil alkalization. Only in organic-mineral fertilizer system variants was noted positive changes in the humus content.
